Novozymes purchases transport services form a variety of different transport providers, in many different countries around the globe, using different types of transport - train, ship, truck and air - with various levels of environmental impact. Differences in environmental impact are largely due to different amounts of fuel per ton product shipped. This makes the transport calculations a highly complex undertaking. Nevertheless, the 2013 transport data cover more than 90% of transport activities.
Data on transport is included under Resource Utilization in The Novozymes Report 2013 and is the third year that we report on data covering all transport activities on a global basis.
Going forward, Novozymes wishes to contribute further to environmental improvements in transport. This requires even closer collaboration with transport providers and ongoing dialogue with customers to further maximize the filling of vehicles.
CO2 emission per transport method for 20 tons moved 1000 km - emission of CO2, NOx, and particles from combustion engines are included:
When data is compared in terms of same volume /distance (see above), it is evident that CO2 emissions varies significant between ship, truck and air.
CO2 emissions in ton divided on type of transport
Transport includes export of sales products from all primary enzymes production sites to first delivery place (covering more than 90% of Novozymes' turnover) and transport between production sites.
Emission is calculated on the basis of principles described in the GHG Protocol - Mobile guide.
Emission figures are either derived directly from suppliers or calculated based on distance and emission factors from the GHG Protocol - Mobile Guide (marked with * in the table).
The calculation practice is based on fuel consumption, distance and weight. The fuel-based appraoch is applied where possible.
